Cagliari are said to be pushing hard for Juventus midfielder Simone Padoin, also liked by Palermo and Fiorentina.
The Sardinians were promoted by winning the Serie B tournament this season after just one year in the wilderness.
According to Sky Sport Italia, Cagliari are making a strong bid for Padoin, who made just 12 Serie A appearances this term, scoring one goal.
The price-tag for the 32-year-old is believed to be €2.5m.
However, Cagliari face competition from Palermo and Fiorentina.
